GAS-HEATED SADJHON.

Application filed February 17, 1911.

sad irons heated by means of gas conducted to said irons through asuitable, flexible tube.

The objects of my invention are to generally improve sad irons of thecharacter mentioned and to provide such construction that the heat fromthe iron body will not be transmitted to the mixer, to the metal partsconnected therewith and to the flexible tube connection.

In many gas heated sad irons heretofore constructed a common fault hasbeen that the heat from the iron body has been transmitted-to the mixer,the metal parts con nected thereto, and the flexible tube connec tion,in some cases even melting the flexible tube connection, thus causingannoyance, damage and great danger. By my invented construction Ipropose to avoid these unclesirable features. 1

The objects above noted, together with other objects readily apparent tothose skilled in the art, I attain by the construction illustrated inthe accompanying drawings, although my invention may be embodied inother forms, the construction illustrated being chosen by way ofexample.

In the drawings Figure 1 is a perspective view of a gas heated sad ironembodying my invention. Fig. 2 is a side elevation of the iron handle,cover, burner and the mixer and its related parts. Fig. 3 is atransverse vertical sectional view of the cover and burner. Fig. 4: is alongitudinal vertical sectional view of the mixer.

Throughout the several views similar reference numerals indicate similarparts.

The numeral 1 indicates the hollow iron body preferably of the formshown in the drawing and having a cut away portion at 2 in its rear wall3. The body 1 is open at the top, the Walls of said body being providedwith the upper edge 4.. For the purpose of closing the top of said body1 the cover 5 is provided, which cover extends from side to side acrossthe top of the body 1 and is provided with the spaced dependingSpecification of Letters Patent.

lugs 6 adapted to rest upon the edge 4: for the purpose of spacing thecover proper from said edge to permit the exhaust of burned gases fromthe interior of the body.

Formed integrally with the cover 5 is the burner portion 7 whichconsists of a tubular structure running longitudinally under the cover 5and spaced therefrom as at 8, said burner being connected to the cover 5by integral connecting portions 9 and 10 at the front and rear endsrespectively.

The burner 7 on its lower side is provided with the transverse slots 11through which the mixed gas and air may pass from the in terior of theburner into the interior of the body of the iron. The burner 7 is closedat its front end but is open at its rear end as shown at 12 in Fig. 1.The cut away port-ion 2 is adapted to receive the humor 7 and connecting portion 10 so that the rear end of the burner 7, when the partsare operatively arranged, will be substantially flush with the external.surface of the rear wall 3. The cover 5 is connected to the body 1 bymeans of the screws 13 or other equivalent means.

Mounted upon the cover 5 and held in spaced relation thereto by thespacing lugs 14 is the handle shield 15 which is con nected to the cover5 by the screw 16 or its equivalent. Preferably formed integrally withthe handle shield 15 are the forward and rear handle uprights 17 and 1Srespectively to which the handle 19 is connected by means of the bolt20. The handle shield 15, being spaced from the cover 5, air will bepermitted to circulate between said cover and handle shield thuspermitting the operator to hold the handle 19 in the hand withoutexperiencing inconvenience from heat radiation from. the said cover.

The mixer 21 and the supporting member 22 are preferably formedintegrally. The member 22 is connected at its upper end to the handleupright 18 by means of the bolt 20 and extends downwardly and curvesrearwardly to the mixer 21. The said mixer consists of a hollow funnelshaped portion 23 provided at its base with air inlet openings 24. whichare formed between the edges of the portion 23 at its base or rear endand the base 25 of the supporting member 22 which extends verticallyacross the base of the mixer as shown in Figs. 1 and l. The smallerforward end of the mixer provided with the exhaust opening 26 is spacedfrom the res wall 3 and the rear end of the burner 7 and is so disposedas to direct the gas and air from said mixer into the interior of theburner 7 through the rear opening 12. Mounted upon the base portion ofthe supporting member 22 is the gas valve casing 27 which is providedwith a screw 28 having a needle point 29 which co-acts with the conicalwalls of the aperture 30 to form a needle valve so that by adjustment ofthe screw 28 more or less gas will be permitted to enter the mixer throuh said aperture 80, as may be desired. For supplying gas to the valve ametallic tube 31, preforably arranged parallel with the supportingmember 22, is connected by the screw threads 32 to the part 27 and aflexible tube 33 for conducting gas to the tube 31 is provided. It willbe understood that the gas conducted by the tube 33 will pass throughthe tube 31 and the interior of the gas valve casing, being projectedforwardly through the aperture 30 and the interior of the mixer 21 intothe interior of the burner '7, whence said gas, with the air drawn inthrough the mixer, will pass through the slots 11, distributing theflame along the bottom of the interior of the iron body 1 from front torear thereof.

It should be especially noted that in so far as any heat may be condcted through the metal to the tube 33 or its connection, such heat willof necessity have to pass through the lugs 14: or screw 16, the handleupright 18, the supporting member 22, the mixer and the tube 31 beforereaching the flexible tube 38 or its connection to the tube 31 It willbe readily apparentto those skilled in the art that very little heatwill thus reach the tube 83. and as the and air are being continuallydrawn in through the mixer 21 and projected into the interior of theburner, very little heat will be transmitted from the burner or ironbody itself to the mixer, across the intervening space,

and that any heat that may be thus con-. ducted will be largelycounteracted by the inrush of air through said mixer. In this way themixer, the metal parts connected therewith and the flexible tubeconnection will be maintained at a comparatively low temperature, thusavoiding the annoyance, damage and danger heretofore commonly attendantupon the use of gas heated sad irons.

I claim In a gas heated sad iron, in combination with a hollow iron bodyprovided with vertical walls, one of said walls provided with a cut awayportion, a cover extending across the top of the body and provided withspaced lugs adapted to rest upon the top edge of the side walls, aburner portion connected to the cover at its front and rear ends anddownwardly spaced therefrom intermediate said ends, the rear end ofsaidburner being adapted to be received into the said cut away portion andprovided with an external opening at the rear end, ahandle shieldconnected to said cover and spaced therefrom by means of spacing lugs, ahandle connected to said handle shield, a mixer supporting memberconnected to the rear' JOHN H.
